> There is currently an issue where inherit copy() from BaseRelNode.  Late in our planning
process, we attempt to uniqify the graph to ensure that no nodes have the same identifier.
 However, the fact that we aren't implementing copy means that we have issues uniqifying.
 We should add the following method to the Prel interface and then implement all required
implementations.
> public abstract Prel copy(RelTraitSet paramRelTraitSet, List<RelNode> paramList);
